What happens if I go overseas? Can I still take part without using roaming?

You can still record your symptoms on the app whilst you are abroad and it will be uploaded when a data connection becomes available (either you connect to WiFi, enable data roaming on your phone or return to the UK). Please note that enabling data roaming while abroad can lead to high costs so please check your mobile phone plan and that you’re happy with the charges if you want to do this.

However, we can only capture weather data within the UK, so your weather data will not be included in the study for any time period that you are abroad.
